Lithium's Crash Sorts Winners From Risks

A month in which Chinese lithium futures slumped on worries about demand ended with a company proposing to add 45,000 tonnes a year of carbonate capacity. Lithium Argentina announced the scoping study on September 30, 2026, Stockhouse reported. The Guangzhou carbonate contract, meanwhile, finished September below 120,000 yuan a ton, down from over 160,000 yuan at the start of the month, according to a Straits Times item republished by Redhot.

That pairing is the story. The September crash is not hitting every lithium project equally. Developers with licences, long-term tax certainty and low costs are still committing money. Producers whose permits depend on a courtroom or a regulator are discovering that a high price protects nothing. The same market now rewards one kind of risk and punishes another.

What China's slump actually says

The slump has a demand story behind it. Bloomberg News, in a report syndicated by MINING.COM, said the futures surrendered almost all of this year's gains on worries over battery demand and inventories. Redhot's republished report adds that China's government suspended construction of new battery projects in September because makers had built too much capacity relative to demand. The contract was around 74,000 yuan in 2025, when the market bottomed.

Benchmark Mineral Intelligence's Adam Megginson framed the fear narrowly. "The story here is not about immediate demand, but worries regarding demand resilience in the mid-term.," he said.

CleanTech Lithium chief executive Ignacio Mehech argues the selloff is noise. "There's no market fundamental behind it, and it should reverse in the short term." he told Bloomberg. His company has reason to talk its book. It is shopping Laguna Verde in Chile, designed for 15,000 tonnes of lithium carbonate a year, and more than 20 companies have signed agreements to review confidential material. Mehech said investor interest is greater than a year ago, reflecting the project's progress and a scarcity of advanced projects globally. He wants a partner this year or early 2027, plus an Australian dual listing by year-end. The project's operating contract sits with Chile's Comptroller General for final review. The AIM-listed company carries a market value of £25.6 million ($33.8 million), and its stock has risen 27% this year, per Bloomberg. Even the confident bidder is waiting on a government signature.

Capital follows certainty

The firmest evidence of appetite comes from Argentina, where the incentive regime is the point. Eramet said in a press release that RIGI offers tax, customs and foreign exchange incentives, together with regulatory stability for 30 years. Eramet's Centenario-Ratones plant reached 90% of nameplate capacity in June 2026, about a year after start-up. The company says it is a full new-generation direct lithium extraction facility at industrial scale outside China. The first plant represents a global investment of approximately US$950 million. Eramet is now contemplating an expansion worth around US$350 million, with a final investment decision possible by end-2027. The expansion would be partly funded by cash from the existing plant.

Lithium Argentina's numbers are bolder. Its study for Cauchari-Olaroz in Jujuy shows an after-tax NPV, discounted at 8%, of $3.1 billion and an IRR of 28.5% at a carbonate price of $18,000/t. Cut the price to $16,000/t and the NPV is $2.5B with an IRR of 25.3%. Operating costs are estimated at US$5,006/t and Stage 2 capital at $1.0 billion. Stage 2 would lift capacity to approximately 85,000 tpa from 40,000 tpa LCE. It has RIGI approval, and the company expects to fund it from internal cash flow and project-level debt, per Stockhouse.

The study still carries a catch. Environmental approval for the full expansion is anticipated during 2027. The first 10,000 tpa adsorption phase, expected online in 2028, needs Chinese authorization to export the technology, which the company says it has not yet obtained. "We are moving immediately to advance a 10,000 tpa first phase using adsorption technology." said chief executive Sam Pigott. Low costs and fiscal stability make the project resilient to price. They do not make it immune to a regulator, in Buenos Aires or Beijing.

The market is sorting, not fleeing. LIT, the lithium and battery ETF, closed at $68.22 on Thursday, dropping 0.29% on the session.

When a ruling beats the price

Sigma Lithium shows the other side. Canadian Mining Journal reports that a federal judge suspended the environmental licences and mining operations at Grota do Cirilo on Sept. 4, in a civil suit brought by the Federation of Quilombola Communities of Minas Gerais, known as N'Golo. The federation says federal mapping puts the Baú community's territory 2.7 km from the operation, inside an 8-km zone that requires prior consultation. Sigma says homes are 8 km to 11 km from its pits. Industrial Info Resources adds that the judge barred Minas Gerais from granting any new licences, expansions or corrective licences until the requested studies are done.

Sigma then halted all mining and processing, two days after dismissing reports of the suspension. Grota do Cirilo is its only producing asset, with annual concentrate capacity of 330,000 tonnes. Brazil's mining regulator ANM separately ordered it to stop mining in part of the complex, citing an unspecified "imminent risk," Reuters reported via MINING.COM. It demanded immediate corrective work on the eastern slope of the north pit, where it described a "ruptured section."

The halt follows a five-week shutdown that ended Aug. 21, after Sigma signed a compliance agreement with Minas Gerais that included up to US$540,000 in fines. Sigma says it will keep up its legal defense, appealing to superior federal courts if necessary. Commercial and recycling activities, including sales of lithium fines, will continue to generate cash, per Mining.com.au. Investing.com, citing Sigma's release, says the suspension affects 12 municipalities in the Vale do Jequitinhonha region.

The balance sheet is thin for a company with no other mine. Sigma produced 35,400 tonnes in the second quarter and sold 24,400 tonnes for US$55 million in revenue. It reported US$17 million in cash and US$125 million net debt at June 30. Its Toronto shares fell 19% to $11.16 by mid-Thursday, leaving them about 40% lower this year.

BMO Capital Markets analyst Joel Jackson cut his 2027 production estimate to 207,000 tonnes from 278,000 tonnes and pushed back the second processing plant to mid-2028 from late 2027. "we move to the sidelines pending greater clarity on a number of legal, safety and environmental challenges facing the company." he said.

Industrial Info Resources notes that the planned expansion would double processing to 3.7 million tonnes of ore a year. It also notes that Brazil's Senate approved a bill on September 2 creating a national policy for critical and strategic minerals, in a country that the USGS ranks as the sixth largest lithium producer. Policy is moving in Brasília while the binding constraints sit with a judge and a regulator.

The lithium price will argue with itself for months, and Mehech may be right that it bounces. A suspended licence does not bounce. It waits for a court.
